The ability to 3D model and print the enclosure and buttons for this project allowed me to make design decisions that would not have been possible using conventional methods. The arrow buttons for example, are not available through any distributor I could find commercially. Additionally the enclosure itself is the exact size (down to the millimeter) to fit my electronics. I believe the conventional idea of using off the shelf parts and fitting your designs into them is coming to an end. The ability to translate my vision for this project to a physical object would not be possible without access to a 3D printer.
